Even though it doesn't play the videos, YouTube still displays recommendations and allows me to search for videos that I then download with yt-dlp. Today it has recommended this video from 18 years ago for no apparent reason: https://www.youtube.com/watch?v=8eHeVQDzEkQ

Maybe because I clicked on some video from nostr:npub1lhjtymyvzee0e6agfvf99sef8jvuh4rapcef7rrmeh5auh8n9kksmud647 so YouTube has decided I like old videos or something.
